PATENT MACHINE FOR SPONGING AND SHRINKING CLOTH.

SPECIFICATION forming part of Letters Patent No. 611,795, dated October4, 1898.

Application filed January 29,1898. Serial No. 668,428. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAVE ROTHHOLZ, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Machines for Sponging and Shrinking Cloth; and I dohereby declare the following to be a full, clear,

and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thereference-numerals marked thereon.

My present invention relates to that class of machines for sponging andshrinking cloth such as shown in myprior patent, No. 511,216, datedDecember 19,1893, and has for its objects to improve their constructionand. operation,whereby the cloth on the cylinder will be dried, and theroller being more thoroughly heated at both ends the dampening of thecovering-felt and the cloth and cylinder by condensed steam will beeffectually prevented; and to these ends it consists in certainimprovements, all as will be hereinafter fully described and the novelfeatures 'pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a side elevation of a machine embodying myimprovements; Fig. 2, a plan view of the same, and Fig. 3 a longitudinalsectional view of the steaming and drying cylinder. I

Similar reference-numerals indicate similar parts.

The main frame of the machine (indicated by 1) may be of the ordinary orany suitable construction, embodying the bench or table 2 for the goodsto be sponged and shrunk and having above said bench guide or tensionrollers 3 3 and on top a stationary steaming-trunk having the perforatedtop 4, the rods 5 at the sides thereof, and the steamsupply pipe 41 atthe end. At the end of the main frame is the winding-roller 6, looselyjournaled in brackets 7, and between this and the trunk is arranged theperforated steaming and drying cylinder containing my presentimprovements. This cylinder is composed of an extension shell 10, ofperforated sheet metal, secured to the hollow or cham bered heads 11 and12, each having journals operating in the bearings 13 13 on the mainframe, the journal of the head 12 having the driving-wheel 14(preferably a gear) secured thereto for causing the rotation of theroller from the driving-shaft 15 through gear 16 thereon. Thedriving-shaft is provided with the belt-pulleys 16 and 17, andthestandard 18, in which the shaft is mounted, has pivoted upon it abelt-shifter 19, as in Figs. 1 and 2. The head 11 of the cylinder, andwhich extends some distance within it, is provided at its outer end witha stuffingbox 20 and gland 21, through which passes a stationarysteam-pipe 22, attached to a T- coupling 40, connected by a pipe 23 witha suitable steam-supply. Arranged within the cylinder and connected withthe inner side of the head is a perforated steam-pipe 24, adapted todischarge the steam entering the hollow head 11 from pipe 23 into theinterior of the cylinder, from whence it passes through the perforationsoutward through the felt and the cloth wound on the cylinder. The outerside of the head 12, at the opposite end of the cylinder-,has theoutwardly-extending tubular extension 25, entering the end of astationary supply-pipe 26, a tight joint between the pipes being formedby a suitable stuffing box 27 and gland 28. Arranged within the cylinderis a steam heating and drying pipe 30, connected at one end with theinner head 12, then coiled around the central pipe 24 toward theopposite end of the cylinder, then extending back toward the head 12 andsecured to the end of the pipe 24, an extension 31 of said pipe 30(smaller than the pipe 24) passing longitudinally through the pipe 24,pipe 22, and a gland 32 on the T-coupling on the pipe 23, and enters theend of an exhaust-pipe 33, in which latter it turns, a steam-tight jointbeing formed by a stuffing-box 34, as shown in Fig. 3.

From the above the operation will be readily understood. The perforatedcylinder having been covered with several thicknesses of felt or similarmaterial the cloth to be sponged or shrunk is placed upon the table 2 atthe rear of the machine and the free end is extended around thetension-rollers 3 3 over the steaming-trunk and wound around thefelt-covered cylinder, and motion being transmitted to the latter fromthe belt-pulley the cloth is steamed and then wound on the cylinder inthe usual manner. Steam having been previously admitted to the pipes 23and 26 passes into the hollow cylinder through the perforations in thepipe 24 and out through the covering and the cloth wound on thecylinder, and the steam, entering the pipe 26, passes through the coilwithin the cylinder and superheating the steam discharged from pipe 24and keeping the cylinder very hot and preventing its chilling andcondensing the steam thereon or within the felt. The cloth is thusheated and shrunk while tightly rolled on the cylinder and is afterwardrolled from the latter on the winding or receiving roller 6 and removedfor subsequent treatment.

The construction herein shown, in which the heads or steam-chambers atboth ends of the perforated cylinder are connected with the live-steamsupply, is a marked improvement over the construction shown in my priorpatent, as both ends of the cylinder are well heated and there is noliability of one end becoming cold and condensing the steam thereon orin the felt, which would dampen the cloth and materially interfere withthe proper operation of the apparatus.

I claim as my invention- 1. In a sponging-machine, the combination withthe revoluble perforated cylinder having the hollow heads orsteam-chambers at opposite ends mounted in bearings and each headconnected directly with a steam-supply, of a perforated pipe connectedto one hollow head and extending lengthwise of and within thecylinder,an im perforate coiled pipe connected with the other head andextending lengthwise of and within the cylinder and having an extendedimperforate portion passing through the opposite head and dischargingoutside of the cylinder, substantially as described.

2. In a sponging-machine, the combination with the revoluble perforatedcylinder having the hollow heads or steam-chambers at opposite endsmounted in bearings, a perforated steam-pipe connected with one of saidheads and extending longitudinally of and within the cylinder, and astationary steam-supply pipe 22 discharging into said head, of animperforate coiled pipe within the cylinder connected to the headopposite the one last men tioned and having an extension passing throughthe opposite head and also through the pipe 22 and discharging outsideof the latter, and a stationary steam-supply pipe connected with thehead to which the coiled pipe is connected, substantially as described.

3. In a cloth-sponging machine, the combination with the frame, thetension-rollers 3, 3 the steaming-trunk having the perforated top andthe rods 5, of the revoluble cylinder having the hollow heads atopposite ends, the perforated steam-pipe 24 within the cylinderconnected to one of the heads, the steam-supply pipe 22 entering saidhead, the imperforate pipe 30 within the cylinder connected to the otherhead, and extending through the pipes 24 and 22 and discharging outsideof the latter, and a steam-supply pipe connected to the head with whichthe pipe 30 communicates, substantially as described.

4. In a sponging-machine, the combination with the revoluble perforatedcylinder,having the hollow heads at opposite ends mounted in bearings,and one of said heads projecting within the cylinder forming a steam-drum therein, a perforated steam-pipe connected with the inner side ofthe drum and extending longitudinally of and within the cylinder, and astationary steam-supply pipe 22 discharging into said head and drum, ofan imperforate coiled pipe within the cylinder connected to the innerside of the head opposite the one last mentioned, and having anextension passing through the opposite head and also through the pipe 22and discharging outside of the latter, and a stationary steamsupply pipeconnected with the outer side of the head to which the coiled pipe isconnected, substantially as described.
